My question comes from a moment when I was riding my bike. I had a flat tire. My question then was how fast do i need to cycle so that i don't ride on my rim's anymore. I tride calculating this with the force that i put on the tire (15kg+70kg= mass of the bike and I)*g= 833,85 N that devided by 2 becaus I ride on 2 tires.=416,925N this force needs to be opposite to the centripetal force and than i would have an 'inflated' tire .This means that Fc= m*ω²*r but in this formula the mass is a point and here the tire is a point so which formula do I need?
